The Basic scales I. section describes the most important scales, i.e. the
seven basic scales, while Basic scales II. section demonstrates these scales
one by one from all the possible twelve starting tones. In the European music
and music theory, the major and minor scales have become predominant among the
basic scales over the decades. The minor scale has three other versions, which
are described in The four types of minor scales section. Tonality wise, the
harmonic minor is of the highest importance out of these
four types of minor
scales; the greatest classical composers and their successors in modern music
have preferred this kind minor to the other ones. In fact, the other five
basic scales got intentionally excluded from classical music theory, and
classified as 'modal scales'. This necessarily meant that the major and minor
scales had become prevalent.

The harmonic minor scales are systematically described in
Harmonic minor scale
degrees I. section. Let's take all the harmonic minor scales degrees from all
the possible twelve starting tones, which makes 12 x 7 = 84 different scale
degrees. The different scale starting notes have been denoted based on the
denotations of the circle of fifths...

...except
for the 6 sharps - 6 flats enharmonic tonalities, where the denotation of D
sharp minor (of the 6 sharps) is used.

Another important thing is the following approach, which is already mentioned
in a previous section:

...Another difference between the harmonic minor scale and the
basic scales is
that each of the basic scale degrees can be used as a separate tonality (hence
the absolute denomination of the scales), whereas in the case harmonic minor
you just can't do the same thing; The harmonic minor defines only one
tonality, and this is the first scale degree (hence the relative denomination
of the scales). I describe this in detail in introduction of the Phrygian
dominant scale section.

Yet, it would still be useful to introduce an absolute scale denomination for
the harmonic minor scale degrees. My students usually successfully comprehend
the basic scales and the relation between them in a few months, and this is
why I find using the same scale denomination for the harmonic minor scales a
very useful thing; for them to see the relation between the basic scales and
the harmonic minor scale degrees.

Here I want to add that this sort of denomination of the harmonic minor scales
only makes the scale identification easier...

Here's a short list of how the scales are denoted:

1st
degree - Minor

2nd
degree - Locrian

3rd
degree - Major

4th
degree - Dorian

5th
degree - Phrygian

6th
degree - Lydian

7th
degree - Mixolydian

Furthermore, the scales can also be played on one string. They are called
one-string scales.

The one-string basic scales are demonstrated in
Basic scales II. section. The
the denomination of the basic scales is absolute (Major, Minor, Phryigian,
etc.), the harmonic minor scales have relative denomination (first degree,
second degree, third degree, etc.). Innovatively, the one-string harmonic
minor scales have a hybrid, absolute-relative, denomination.

As an example, here's this: There is an E Harmonic Minor full scale
structure...

...and the one-string E harmonic minor scale started from the A string...

...This one-string scale is actually the fourth degree, which is the Dorian
degree (it only differs from a normal Dorian scale in one altered note). One
more note: the notes in this one-string scale reflect the number of the notes
in the full scale structure above.
